Timing shim set for indexing a free-float AR-15 barrel nut. The shims let you align the gas-tube hole and handguard while staying inside torque spec, so you do not have to over-torque the nut to clock it correctly.

Features:

• Set of 5 timing shims
• Times and indexes free-float barrel nuts
• Keeps the gas-tube hole aligned within torque spec
• For .223/5.56 free-float barrel nuts

Use these shims to dial in barrel-nut alignment without exceeding the recommended torque range on your free-float build.
